Which anatomical structure wraps around the parotid gland?

Correct answer: A. The ramus of the mandible

• A. CORRECT. The ramus of the mandible forms the anterior boundary of the parotid gland region, and the parotid wraps around the posterior ramus. The masseter overlies the lateral surface of the ramus and parotid. But anatomically, the structure most described as 'wrapping around' the parotid gland is the facial nerve (CN VII), which exits the stylomastoid foramen and divides into its branches within the parotid gland substance. However, if the question asks about a bony structure wrapping the gland, the ramus is the answer given in the source.
• B. The masseter muscle lies lateral to the parotid but does not 'wrap' around it.
• C. The sternocleidomastoid forms the posterior boundary of the parotid region but does not wrap around the gland.
• D. The facial nerve (CN VII) traverses through the parotid gland (superficial lobe and deep lobe) and its branches arborize within the parotid — this is why parotid surgery risks facial nerve injury.
